'Understand Book of Daniel'
Dan 12:1 "At that time Michael shall stand up, The great prince who stands watch over the sons of your people; And there shall be a time of trouble, Such as never was since there was a nation, even to that time. And at that time your people shall be delivered, every one who is found written in the book.
These Jews have their names written in the Book of Life. They must have been convicted by the dreams and visions and the messages of the martyrs. They must have shared the gospel with fellow Jews and had refused to bow down to the Antichrist during dedication. With the help of Michael the Archangel, these Jews appear to be like born again Christians.
Phi 4:3 And I urge you also, true companion, help these women who labored with me in the gospel, with Clement also, and the rest of my fellow workers, whose names are in the Book of Life.
Rapture happen during a very short period of possibility of a couple of minutes. Immediately after the great earthquake worldwide, everyone will run to open ground.
Once we can synchronize Rapture from the various books, we can see end time events clearly.
In Daniel 11-12, it is clear that after WW3 (4th Seal) will be a period of the greatest trouble for the Jews (5th Seal - Great Tribulation), then comes the salvation of the 144,000 Jews (6th Seal - Rapture for Christians)
Mat 24:29-30 "Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of the heavens will be shaken. Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory."
Just before Rapture, the whole heaven (sun and moon darkened) will be darkened so that our Lord with the heavenly hosts coming from heaven will appear as stars falling from the heaven.
Rev 6:12-13 I looked when He opened the sixth seal, and behold, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became like blood. And the stars of heaven fell to the earth, as a fig tree drops its late figs when it is shaken by a mighty wind.
Joel 2:30-32 "And I will show wonders in the heavens and in the earth: Blood and fire and pillars of smoke. The sun shall be turned into darkness, and the moon into blood, before the coming of the great and awesome day (Rapture) of the LORD."
Luke:21.11-12a "And there will be great earthquakes in various places, and famines and pestilences (4th Seal); and there will be fearful sights and great signs from heaven (6th Seal). But before all these things, they will lay their hands on you and persecute you, delivering you up to the synagogues and prisons. (5th Seal)"
The numbering of the verses is poor and that is why most cannot comprehend this part.
4th Seal - is WW3 and the natural calamities.
6th Seal - signs in heaven in Luke 21:25-27, but before these signs will be the 5th Seal or persecutions and martyrdom.
Luke 21:25, 27 "And there will be signs in the sun, in the moon, and in the stars; and on the earth distress of nations, with perplexity, the sea and the waves roaring;... Then they will see the Son of Man coming in a cloud with power and great glory."
So Rapture in Mat 24:29-31 is the same event as Mark 13:24-27, Rev 6:12-15, Joel 2:30-32, Luke 21:11b and Luke 21:25-27, etc.
